3 How to get computer name using java

There's no universal concept of a computer name across OSes, but DNS is generally available. If the computer name hasn't been configured so DNS can resolve it, it isn't available.

String hostname = "Unknown";

try
{
InetAddress addr;
addr = InetAddress.getLocalHost();
hostname = addr.getHostName();
}
catch (UnknownHostException ex)
{
System.out.println("Hostname can not be resolved");
}
